Description

Technical Field

[0001] The present application belongs to the technical field of protective devices, and in particular, relates to a camera lens protective device and a camera device. Background Art

[0002] At present, camera equipment needs to be installed in many application scenarios, such as visual recognition and traditional scene monitoring. However, the lens end of traditional camera equipment is usually an exposed transparent panel. During long-term use, pollution sources such as dust, smoke and metal chips will adhere to the panel, resulting in spots or blurred images during imaging, which will directly affect the accuracy of visual recognition. In order to maintain the clarity of the imaging of the camera equipment, the transparent panel of the lens needs to be cleaned and maintained regularly, and the frequency of maintenance mainly depends on the degree of pollution in the environment where the camera equipment is located. The degree of pollution of the lens of camera equipment used indoors is generally relatively light, while the frequency of cleaning of camera lenses for outdoor use, such as mining, construction sites, and road transportation waiting environments, will be greatly increased; moreover, there are professional methods and steps required for cleaning operations during cleaning. Some camera equipment is also usually installed in inaccessible locations such as high altitudes, requiring professional equipment and tools to cooperate, so frequent cleaning operations will bring great maintenance costs. Summary of the invention

[0003] In order to overcome at least one disadvantage of the above-mentioned prior art, the purpose of the present application is to provide a camera lens protection device and a camera equipment.

[0004] The technical means adopted by this application to solve the above technical problems are:

[0007] In the embodiment scheme of the present application, by installing the plurality of imaging channels on the camera lens, it can be ensured that when the camera is in use, external water vapor and dust cannot directly act on the camera lens, thereby achieving dustproof and water vapor-proof effects, extending the application cycle of the equipment, and reducing the cleaning frequency and application cost of the equipment; moreover, the formation of the dustproof effect will not affect the normal use of the camera, and the use will be more convenient.

[0008] In some embodiments, an oblique cut is provided at the extended end of the imaging channel, and a longer distance segment formed by the oblique cut is located above a shorter distance segment.

[0009] In the embodiment of the present application, the oblique cut can be provided to facilitate forming a certain shielding effect, so as to prevent dust and the like from falling into the imaging hole from above the imaging hole, thereby further improving the dust prevention effect.

[0010] In some embodiments, at least a portion of the extended ends of the imaging channels are partially closed, and the partially closed surface formed at the extended ends of the imaging channels is transparent.

[0011] In the embodiment of the present application, by setting the extended ends of at least part of the imaging channels to be transparent and partially closed, it is ensured that when individual imaging channels are blocked, some of the imaging channels can still be in normal working condition.

[0012] In some embodiments, it further comprises a barrel, wherein the plurality of imaging channels are disposed in the barrel;

[0013] The extended ends of the plurality of imaging holes are flush with the end of the barrel; or, there is a preset gap between the extended ends of the plurality of imaging holes and the end of the barrel.

[0014] In the embodiment of the present application, by designing the length of the imaging channel in the cylinder, the device can be designed and applied according to different application requirements.

[0015] In some embodiments, the starting end of the cylinder is provided with a transparent wall in a closed manner, and the starting ends of the plurality of imaging channels are sealed and connected to the transparent wall to form the closed end;

[0018] In some embodiments, the cross-sectional shape of the cylinder and / or the imaging channel is at least one of circular, elliptical and polygonal.

[0019] In the embodiment scheme of the present application, by designing the cross-sectional shape of the cylinder and / or the imaging channel, the influence of the wall structure formed between two imaging channels or between multiple imaging channels on the imaging of the camera can be reduced.

[0020] In some embodiments, the plurality of imaging channels are arranged in sections along their axial direction, including a first imaging channel section and a second imaging channel section;

At the same time, the camera device can be applied to more working conditions, thereby improving the application efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the present invention, and the embodiments described are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present invention.

[0049] It should be noted that: unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art of the technical field of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. Similar reference numerals and letters represent similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0050] like Figure 1-11 As shown, in this embodiment, a camera lens protection device is provided, comprising a plurality of imaging holes 2, one end of each of the plurality of imaging holes 2 being a closed end, and the closed end being arranged toward the camera lens; the other end of each of the plurality of imaging holes 2 extending toward the outside, and at least some of the extended ends of the imaging holes 2 being arranged as an open end. Each of the imaging holes 2 is configured to allow the camera lens to capture the object through the interior of the imaging hole 2.

[0051] In some embodiments, the camera lens may be a telephoto lens or a wide-angle lens. When the protective device is applied to a telephoto lens, the plurality of imaging channels 2 are arranged side by side with their axes parallel to each other to keep matching with the captured light of the telephoto lens. Figure 1 , 2 When the protective device is applied to a wide-angle lens, the plurality of imaging channels 2 are arranged in a trumpet shape, and an angle is formed between the axis of the imaging channel 2 located on the outside and the axis of the imaging channel 2 located in the center, so as to keep the image matching the captured light of the wide-angle lens. Figure 3 shown.

[0052] By setting the plurality of imaging channels 2, and making one end of the imaging channel 2 a closed end, and the other end at least partially in the form of an open setting; after the plurality of imaging channels 2 are installed on the camera lens, the camera lens can be shielded to prevent dust and water vapor from directly condensing on the camera lens; and, since the end of the imaging channel 2 close to the camera lens is a closed end, the internal pressures at both ends of the imaging channel 2 are different. After the microparticle molecules enter the slender imaging channel 2, due to the collision between molecules and the collision and adhesion with the inner wall of the imaging channel 2, it will be difficult for dust and water vapor molecules to enter the closed end of the imaging channel 2. Even if it is used in an environment where water vapor or dust is more serious, water vapor and dust will first adhere to the inner wall of the imaging channel 2. The plurality of imaging channels 2 can form a larger area of ​​the inner wall structure to provide a large amount of water vapor and dust for attachment, thereby achieving the application effect of dust and water vapor, thereby facilitating the extension of the application cycle of the equipment and reducing the cleaning frequency and application cost of the equipment.

[0053] In addition, based on the design of dustproof and water vapor proof, some corresponding solutions are also proposed on the market. In these solutions, a dust cover is usually set in front of the camera lens. When the camera is in an idle state, the dust cover is driven to cover the camera lens. However, although this method can achieve a certain protective effect, it can only be used when the camera is in an idle state; the protective device provided in the embodiment will not affect the normal use of the camera lens, and it will be more convenient to use.

[0054] As one application example, an oblique cut 11 is provided at the extended end of the imaging channel 2, and a longer distance segment 111 formed by the oblique cut 11 is located above a shorter distance segment 112, such as Figure 4 , 5 , 7, and 8.

[0055] In some embodiments, the oblique cuts 11 provided at the extended ends of the plurality of imaging channels 2 together form an oblique cut surface. Figure 5 As shown, the protective device at this time is mainly used for wide-angle lenses, and the oblique cuts 11 are formed at the front end and the lower half of both sides of the protective device; Figure 7 , 8 As shown, the protective device at this time is mainly used for a telephoto lens, and the oblique cut 11 is formed at the front end of the protective device.

[0056] The oblique cutout 11 can be provided to provide a certain shielding effect, so as to prevent dust from falling into the imaging hole 2 from above the imaging hole 2, thereby further improving the dust prevention effect.

[0057] Moreover, it is found in actual applications that dust is usually formed by rolling up from the bottom with the airflow, or falling down from the top with the airflow, and it is rare for the dust to be blown in from the axial direction of the imaging channel 2; therefore, by setting the extended end of the imaging channel 2 in the form of the bevel cut 11, when the dust rolls up from the bottom with the airflow, the airflow and the dust will touch the inner wall of the longer section 111 of the bevel cut 11, and then most of the dust will fall directly to reduce the amount of dust retained in the imaging channel 2; and when the dust falls from the top with the airflow, the outer wall of the longer section 111 of the bevel cut 11 can be used to block it, which can also reduce the amount of dust retained in the imaging channel 2, so as to avoid dust from falling from the top of the imaging channel 2 into the imaging channel 2. The design is ingenious and can further improve the dust-proof effect of the device.

[0058] As one application example, at least part of the extended end of the imaging channel 2 is partially closed, and the partially closed surface 23 formed at the extended end of the imaging channel 2 is transparent. Figure 10-11 , as shown in 13-14.

[0059] In some embodiments, the extended end of part of the imaging channel 2 is semi-closed; for example, when the cross-sectional shape of the imaging channel 2 is circular, the semi-closed surface formed at the extended end of the imaging channel 2 is semicircular and transparent; at this time, particulate molecules such as water vapor and dust can still enter the imaging channel 2 from the semicircular opening of the other half of the imaging channel 2.

[0060] In some embodiments, Figure 9-11 As shown, the cross-sectional shape of the imaging channel 2 is a regular hexagon, and the partially enclosed surface 23 is a trapezoid. Fig.10 , 11 shown.

[0061] In some embodiments, Figure 12-14 As shown, the cross-sectional shape of the imaging channel 2 is rectangular, and the partially enclosed surface 23 is rectangular. Fig.13 , 14 shown.

[0062] In some embodiments, the partially closed surface 23 formed by the extended end of the imaging channel 2 is located above the axis of the imaging channel 2. Figure 10-11 , as shown in 13-14.

[0063] By setting the extended end of at least part of the imaging channel 2 to be transparent and partially closed, it is ensured that when individual imaging channels 2 are blocked, part of the imaging channels can still be in a relatively normal working state, so that the camera lens can capture images through the partially closed surface 23 formed.

[0064] As an application example, the protective device in this embodiment further includes a cylinder 1 , and the plurality of imaging channels 2 are arranged inside the cylinder 1 .

[0065] In some embodiments, for example, when applied to a telephoto lens, the extended ends of the plurality of imaging holes 2 are flush with the end of the barrel 1. At this time, the end of the barrel 1 and the ends of the plurality of imaging holes 2 together form the beveled surface. Figure 1 , 7 shown.

[0066] In some embodiments, for example, when applied to a telephoto lens, a preset gap 12 may be provided between the extended ends of the plurality of imaging channels 2 and the end of the barrel 1. In this case, the length of the imaging channel 2 is set to be less than the length of the barrel 1. Figure 2 , 8 In this application, the oblique cut 11 is still retained at the end of the cylinder 1, and the end of the imaging channel 2 can be set in the form of a flat cut or an oblique cut; in application, the dust will first fall on the inner wall surface of the preset gap 12 between the cylinder 1 and the end of the imaging channel 2.

[0067] In some embodiments, for example, when used in a wide-angle lens, the barrel 1 can be configured as a baffle made of a transparent material, so as to shield and protect the upper part of the protective device to prevent pollution sources such as dust from directly entering the imaging channel 2 from above; while the front end, both sides and bottom of the protective device are kept open to prevent the setting of the barrel 1 from affecting the imaging effect, such as Figure 3-5 shown.

[0068] In some embodiments, the plurality of imaging channels 2 are provided in plurality, such as two or more than two, and the plurality of imaging channels 2 are arranged side by side to form a honeycomb channel structure, such as Figure 1 , 2 , 3; the extension length of the cylinder 1 is related to the aperture of the imaging channel 2 or the density of the formed honeycomb channel structure. For example, when the aperture of the imaging channel 2 is small, or the density of the formed honeycomb channel structure is dense, the extension length of the cylinder 1 can be relatively set to be shorter; on the contrary, if the aperture of the imaging channel 2 is large, or the density of the formed honeycomb channel structure is sparse, the extension length of the cylinder 1 can be relatively set to be longer; and the specific size design can be adjusted according to the dustproof requirements and water vapor proof requirements of the application environment.

[0069] In some embodiments, the number of the imaging channels 2 can also be set to one, in which case the overall length of the imaging channels 2 needs to be designed to be longer to meet the internal pressure settings at both ends of the imaging channels 2, and to allow the microparticle molecules to have a sufficiently long collision and attachment path from the extended end of the imaging channels 2 to the closed end of the imaging channels 2. In actual experiments, it was found that when the number of the imaging channels 2 is set to one, for example, in the application of a telephoto lens, the imaging channel 2 can be considered to be equivalent to the barrel 1, and under the premise of meeting the designed dustproof effect, the overall length of the imaging channel 2 is relatively long, and the application benefits are not as good as when the imaging channels 2 are set to multiple.

[0070] By designing the setting length of the imaging channel 2 in the cylinder 1, it is possible to facilitate the application of the protective device according to different application environments and requirements, while taking into account the processing and manufacturing benefits; and the setting of the inner wall surface of the imaging channel 2 and the cylinder 1 can ensure that even if water vapor and dust adhere, they will first adhere to the imaging channel 2 and the inner wall of the cylinder 1, and will not directly affect the camera lens.

[0071] In some of the application tests, even if individual imaging channels 2 are blocked, it will not have much impact on the object capture and final imaging of the camera lens. However, in general application environments, it takes a very long time to block a single imaging channel 2 through the natural movement of the dust itself, which is much longer than the current maintenance cycle for cleaning the camera lens.

[0072] In some embodiments, the starting end of the cylinder 1 is provided with a transparent wall in a closed manner, and the starting ends of the plurality of imaging channels 2 are sealed and connected to the transparent wall to form the closed end.

[0073] In some embodiments, the beginning of each imaging channel 2 is closed and provided with a transparent wall.

[0074] At this time, the closed end may be formed by a sealed connection between the imaging hole 2 and the barrel 1; or a transparent wall may be provided at the beginning of the imaging hole 2 to form the closed end.

[0075] As one application example, the cross-sectional shape of the barrel 1 and / or the imaging channel 2 is at least one of a circle, an ellipse and a polygon. Figure 4 , 9 , as shown in 12.

[0076] In some embodiments, the cross-sectional shape of the barrel 1 is set to be consistent with the shape of the camera lens, such as being set to be circular; in some other application examples, it can also be set to be elliptical or polygonal.

[0077] In some embodiments, the cross-sectional shape of the imaging hole 2 can be set to be consistent with the cross-sectional shape of the barrel 1, such as setting the cross-sectional shape of the imaging hole 2 and the cross-sectional shape of the barrel 1 to be circular.

[0078] In some embodiments, the cross-sectional shape of the imaging channel 2 can be set to be different from the cross-sectional shape of the barrel 1. For example, when the cross-sectional shape of the barrel 1 is set to be circular, the cross-sectional shape of the imaging channel 2 can be set to be polygonal.

[0079] In some embodiments, the cross-sectional shape of the imaging channel 2 is set to be a regular polygon, such as Figure 1 , 9 As shown, the cross-sectional shape of the imaging channel 2 is a regular hexagon; Figure 2 , 12 As shown, the cross-sectional shape of the imaging hole 2 is rectangular; at this time, the adjacent imaging holes 2 can share the wall structure, so that the thickness of the wall structure between the adjacent imaging holes 2 can be better controlled, so as to further reduce the influence of the setting of the imaging hole 2 on the imaging of the camera lens.

[0080] By designing the cross-sectional shape of the barrel 1 and / or the imaging hole 2, the influence of the wall structure formed between two imaging holes 2 or between a plurality of imaging holes 2 on the imaging of the camera lens can be reduced.

[0081] As one application example, the plurality of imaging channels 2 are arranged in sections along their axial direction, and an example is given here when the imaging channel 2 is arranged in two sections. In this case, the imaging channel 2 includes a first imaging channel section 21 and a second imaging channel section 22, wherein the diameter width of the imaging channel 2 in the second imaging channel section 22 is greater than the diameter width of the imaging channel 2 in the first imaging channel section 21.

[0082] In some embodiments, Fig. 9 As shown, the cross-sectional shape of the imaging hole 2 in the first imaging hole section 21 is set to a regular hexagon, and the cross-sectional shape of the imaging hole 2 in the second imaging hole section 22 is a shape surrounded by the outer side surfaces of seven regular hexagons arranged side by side, and one of the regular hexagons is centrally arranged; at this time, within the coverage range of the imaging hole 2 in the second imaging hole section 22, seven imaging holes 2 in the first imaging hole section 21 are arranged.

[0083] In some embodiments, Fig.12 As shown, the cross-sectional shape of the imaging channel 2 in the first imaging channel section 21 is set to be a rectangle, and the cross-sectional shape of the imaging channel 2 in the second imaging channel section 22 is also a rectangle; at this time, within the coverage range of the imaging channel 2 in the second imaging channel section 22, nine imaging channels 2 in the first imaging channel section 21 are arranged.

[0084] In some embodiments, when the imaging hole 2 is provided with a plurality of diameter width specifications, the diameter width of the imaging hole 2 in the first imaging hole section 21 is smaller than the diameter width of the imaging hole 2 in the second imaging hole section 22, and so on.

[0085] In some embodiments, the diameter width of the imaging hole 2 in the first imaging hole section 21 is relatively small, and the first imaging hole section 21 is arranged close to the camera lens.

[0086] In some embodiments, the number of segments of the imaging hole 2 can be set to be greater than 2, and the number of segments of the imaging hole 2 corresponds to the number of diameter and width specifications of the imaging hole 2.

[0087] By configuring the imaging hole 2 to include two or more segments, and allowing the imaging holes 2 corresponding to different segments to have different diameter and width specifications, a segmented protective effect can be formed at the extended end of the barrel 1 toward the camera lens, and the protective effect is in the form of layer-by-layer enhancement; in addition, the imaging hole 2 with a larger diameter and width value is configured close to the extended end of the barrel 1, and at this time, it is also convenient to clean the imaging hole 2 located on the outside.

[0088] In some embodiments, a drainage hole can be opened on the bottom wall surface of the extended end of the imaging channel 2 to facilitate the discharge of water vapor after condensation; or, the peripheral surface of the extended end of the imaging channel 2 can be set as a mesh structure surface, so as to facilitate the hydrophobic drainage effect and improve the waterproof performance of the device.

[0089] As one application example, the protective device also includes a mounting plate 3, and the cylinder 1 and the imaging channel 2 are both arranged on the mounting plate 3; the mounting plate 3 and the camera lens are detachably connected.

[0090] In some embodiments, a plurality of mounting holes 31 are provided on the mounting plate 3 and the camera lens, and fasteners such as bolts are provided corresponding to the mounting holes 31. The fasteners are installed on the mounting holes 31 to achieve the installation and fixation between the mounting plate 3 and the camera lens.

[0091] In some embodiments, the mounting plate 3 can be made of transparent materials, such as glass and transparent plastic plates, etc. At this time, the mounting plate 3 can be used as a transparent wall surface at the beginning of the cylinder 1 or as a transparent wall surface at the beginning of the imaging channel 2.

[0092] By providing the installation fixing plate 3, it is possible to facilitate the installation of the entire protective device on the camera lens, thereby achieving detachable matching use.

[0093] As one application example, a sealing strip 32 is provided on the side of the mounting plate 3 facing away from the cylinder 1 , and the enclosing shape of the sealing strip 32 is adapted to the shape of the camera lens.

[0094] In some embodiments, a transparent protective plate is provided at the camera lens end, and the transparent protective plate is provided in a rectangular shape, and the sealing strip 32 is provided in a square frame shape corresponding to the transparent protective plate. Figure 6 shown.

[0095] By setting up the sealing strip 32, it is possible to avoid the pressure loss of the camera lens caused by the mounting plate 3 during installation, and it can also play a sealing protection effect to prevent water vapor and dust from entering from the installation gap between the mounting plate 3 and the camera lens.

[0096] On the other hand, this embodiment also provides a camera device, including a camera lens, on which the camera lens protection device as described above is arranged.

[0097] By adding the camera lens protection device to the camera equipment, the service life of the camera equipment can be extended, the frequency of cleaning the lens of the camera equipment can be reduced, and the camera equipment can be applied to more working conditions, thereby improving application benefits.

[0098] For example, with the rapid development of AI, AI vision has been widely used. In the field of visual measurement applications, visual measurement relies on the camera lens to accurately capture and analyze the image information of the object to be measured to calculate parameters such as size, shape, position, angle, etc. Any factors that affect the image quality, such as image blur caused by dust, increased noise, decreased contrast, etc., will directly affect the accuracy of the measurement results. By adopting the protective device proposed in the embodiment, the duration of the clean state of the lens surface and internal optical elements can be extended, which is convenient for the camera equipment to output high-definition, interference-free images, thereby ensuring the accuracy of visual measurement.

[0099] Moreover, visual measurement systems usually need to run continuously for a long time, and in some industrial environments, they may be exposed to pollution sources such as dust, smoke, and metal chips. Dust accumulation will not only reduce the accuracy of a single measurement, but also cause the system performance to gradually decline, affecting the overall measurement stability. By adopting the protective device proposed in this embodiment, it can help reduce the downtime caused by maintenance and cleaning work, and maintain the long-term stable operation of the system.

[0100] In addition, in special fields such as aerospace, precision manufacturing, field research, geological exploration, etc., visual measurement equipment may need to work in extreme environments (such as high temperature, low temperature, high humidity, sandstorms, etc.). By adopting the protective device proposed in this embodiment, the normal operation and accurate measurement of the camera equipment in these harsh environments can be improved, and dust, moisture, salt spray, etc. can be prevented from damaging optical components and electronic devices.

[0101] In traditional monitoring applications, dust, dirt and other particles attached to the lens surface will cause light scattering or blocking, seriously affecting the image quality, causing blur, spots, color difference and other problems, reducing the picture clarity and detail presentation ability. For monitoring scenarios that require precise calculations for geological disasters such as landslides, traffic bridges and tunnels, mine collapses, house construction, etc., it will seriously affect the calculation results, resulting in misjudgments and wrong judgments. In the fields of security monitoring, traffic monitoring, industrial inspection, etc., the camera lens needs to accurately capture and record important details, such as license plate numbers, facial features, and minor defects on the production line. Correct results will not be obtained. By adopting the protective device proposed in this embodiment, this kind of situation can be prevented from happening, ensuring that the camera continues to provide high-definition video or images; and avoiding information loss or misjudgment caused by dust interference, ensuring the accuracy and reliability of the monitoring system.

[0102] In addition, dust entering the camera lens may not only directly damage the lens, but may also adhere to electronic components, sensors and other parts, causing problems such as poor heat dissipation, circuit short circuits, mechanical jams, etc., accelerating equipment aging and shortening service life. For cameras installed in complex environments such as outdoors, factories, mines, and farmlands, if they do not have good dustproof performance, they may need to be cleaned or repaired frequently, increasing operating costs. By adopting the protective device proposed in this embodiment, the internal components can be protected from dust and the camera lens can be ensured to work stably for a long time. It can also significantly reduce the demand for such maintenance and save manpower and material investment.
